While the components of the "savory and sweet breakfast treat" make it seem like a heart-stopper, Dunkin' Donut patrons may be surprised to learn the coming 360-calorie sandwich has 30 fewer calories than the newly released turkey sausage sandwich, according the The Associated Press.

The sandwich consists of a fried egg and bacon inside a split glazed donut and will be available June 7 on National Donut Day.

The sandwich created buzz in April when Dunkin' began testing in eastern Massachusetts.
